Never be afraid to ask! Whether it’s at a restaurant or buying wine, if you aren’t sure, ask! Most of the time, wine stewards and servers love discussing their knowledge of wine.
Taste, taste, and re-taste! I was never a fan of Riesling, until I tried French Riesling. Different areas can make a huge difference.
Last, don’t be afraid to talk about what you like. If your favorite is an $8 bottle of White Zin, great! Never feel bad for liking a certain kind of wine.
As for cheese, some can be expensive. Don’t be afraid to ask them to cut a smaller portion to take home. And if you want to cook with the cheese, googling recipes is your best friend!
